PDFFiller has allowed me to complete processes that I would have otherwise been unable to do. The service is somewhat easy to use and has quite a large range of features that have been a huge benefit for me.

I love it but when I was trying to edit document I could only click and erase some fields. I had to use the eraser for the rest. But overall great product.

This software seems to be nice and easy to use, im still working my way round it. I was looking to send a form to be returned filled in. Looks like this should be easy enough. I will keep my fingers crossed.

What do you like best?
Easy to use, anyone who I've sent a file has had no issues receiving and downloading. Some of them have told me they've gone on to use the product regularly themselves.
What do you dislike?
Nothing to do with pdffiller, but I sometimes forget to set up the files I'm uploading in the right folders. That's on me.
What problems are you solving with the product? What benefits have you realized?
Under the 'documents' tab, the 2 columns on the right could be made more distinctly different from each other to denote they are in fact different. They are just two shades of gray and not that different in tone.

I just was able to get the best service…
I just was able to get the best service ever from Paul. I found I did not use this service as much as I did in the past, but the automatic renewal of payment had gone through. I contacted CS via Support and received a FULL Refund and cancellation of Auto Pay with in 3 minutes flat. Furthermore, received an email with confirmation of my request!! This is the way to do business!! Thank you for making the refund process painless!

My experience with PdfFiller was great
My experience with PdfFiller was great. I use PdfFiller as a cloud storage for backup files, in addition I can multitask by retrieving signed documents and save them in my signed doc. file for later.

The card reading company kept declining…
The card reading company kept declining every card I had even though they were all in good standing. Customer Service (online chat) tried several remedies. Still did not work. I needed to print the document I completed. Customer Service gave me a one time free print so I was not in a bind and will try again tomorrow from different computer to actually purchase the service!!Thank you!!
